If I got 10 endurance and have 80 % critical endurance and I will take perk critical endurance it will stack to 105 %?
Yes. But some weapon perks and certain effects governed by endurance might have reduced resistance. For example, Endurance affects arm cripples, and if your enemy has the "Crippling Strike" weapon perk, you will suffer -2 to your endurance roll to resist that effect. That translates to -10% resistance, so your resistance in such a case would then be 105-10 = 95%.
In any case, 10 in any stat + critical <stat> perk will make it exceedingly rare for you to suffer any critical effects associated with that stat. But it can still happen, in some cases!
Does perk action boy improve rengeration AP during running AND staying in one place(12,5+2=14,5?) or only during runing?
There are two forms of AP regen. One happens only when you stand still, and gives 12.5 AP/s. This works just like normal AP regen on other servers, except since your AP is always 100, the normal AP regen is always 12.5/s.
The second AP regen, called "Ap regen+" because we're too unimaginative to come up with a proper name, gives you AP all the time (except for some special cases like when you are healed by super stimpaks, and just after firing weapons that don't have the double-tap trait). The AP regen+ is based on your agility, and the Action Boy perk acts as if your agility was +2 for the AP regen+ calculation.
If I will take perk gain inteligence on 24 lvl it will give me back all points skill lost from 1 lvl to 24?
Yes. You may have to close and open your character sheet to see your new skill points though.
If I got 330 hp when adrenaline rush perk will give me max bonus?
Adrenaline rush gives bonus DR according to this formula:
DR += 10 - 10*currentHP/maxHP
When Do or Die perk will give me max bonus(50 % hp???)?
Do or Die gives you bonus AP regen+ when your HP drops, according to this formula:
BonusAp/s = 2 - 2*currentHP/maxHP
What is a formula for first aid? For example how many hp I will heal with 150 fa using on me or friend while 0 % bandaged or 50 % bandaged.
The bandaged status is a percentage that reduces the amount healed. If you have for example 20% bandaged, any healing with FA will only heal 80% of the amount it otherwise would have.
Each HP healed with FA will increase your bandaged status by 1/3 points, except if you have the faith healer perk, in which case it increases bandaged by 1/6 points.
The base amount healed with FA depends on several things, most importantly your FA skill. However, if your FA is low but your doctor is high, some of your doctor skill will count as FA skill instead. If you have 200 doctor skill, that counts as 175 FA for the purposes of healing Hit Points. If you have the Medicinae Doctor perk, 200 Doctor skill will count as 200 FA for healing Hit Points.
The base amount healed is given by:
HitPointsHealed = 50 + MAX(skill-100,0)
The Dr. Strangelove perk gives +50 to that number, and the "Improved healing" item perk/trait from first aid kits/doctor bags gives +25. The "Easier to Heal" armor trait gives +25, and the "Harder to heal" armor trait gives -25.
